POWERPC ALLIANCE ANNOUNCES FIRST MAINSTREAM DESKTOP
MICROPROCESSOR TO REACH THE NEXT GENERATION OF PERFORMANCE

Doubles PowerPC Chip Performance in Less Than a Year

AUSTIN, TX, June 12, 1995 -- IBM and Motorola today unveiled two
high-powered extensions to the PowerPC 604t line of RISC-based
microprocessors, establishing a new level of PowerPC chip performance
for desktop personal computers.
These new versions of the PowerPC 604 microprocessor operate
at 133 and 120 MHz, performance that exceeds Intel's current Pentium
offerings and is comparable to the future P6 microprocessor. With
this announcement, IBM and Motorola double desktop PowerPC chip
performance in less than a year and offer the first mainstream
desktop microprocessor capable of achieving a SPECint92 performance
rating of 200.
"Today, our slowest PowerPC 604 processor outperforms Intel's
fastest PC microprocessor," said Ron Black, director of PowerPC
microprocessor marketing, IBM Microelectronics Division. Continued
innovation and investment by the Apple, IBM, Motorola development
alliance allows us to develop and incorporate the most advanced, next
generation technologies, including Reduced Instruction Set Computing
(RISC), faster floating point operations and superscalar
implementation. That's how we will maintain our processor lead."
"By introducing these new PowerPC 604 chips, the alliance
continues to show its strength and commitment to deliver the
industry's next microprocessor standard," said Phil Pompa, director
of marketing, Motorola RISC Microprocessor Division. "The PowerPC
604 at 133 MHz provides unsurpassed processor performance for
high-performance desktop and server applications."
The new PowerPC 604 processors are expected to show up in
desktop systems soon. The imminent arrival of systems based on 133
and 120 MHz PowerPC 604 microprocessors illustrate the growing ease
of leveraging PowerPC performance. Like all other PowerPC
microprocessors, the two new chips combine superior performance with
the ability to run the fullest range of operating systems and
applications.
Organizations that have announced systems or plans to
develop PowerPC microprocessor-based systems include: Apple
Computer, Canon, DayStar Digital, FirePower Systems, Groupe Bull,
Harris, Hitachi, IBM, IPC Technologies, Parsytec, Power Computing,
Pioneer, Radius, Tadpole, Tatung, Thomson-CSF, Toshiba and YARC. In
addition, the Taiwanese New PC Consortium has announced its
endorsement of the PowerPC architecture and China's Ministry of
Electronics industry has agreed to help promote the use of PowerPC
technology and the development of supporting software in China.

Technical Specifications - PowerPC 604 120 MHz and 133 MHz
The 133 MHz PowerPC 604 processor has an estimated SPECint92
rating of 200 and an estimated SPECfp92 of 200. The 120 MHz PowerPC
604 microprocessor is capable of an estimated SPECint92 rating of 180
and an estimated SPECfp92 performance rating of 180. Each
microprocessor has dual 16K byte instruction and data caches, a die
size of 12.4 mm x 15.8 mm and an IEEE-754 compliant floating point
unit. They each have 3.6 million transistors and were designed using
0.5- micron process technology.
Both IBM and Motorola will manufacture the higher-speed
versions of the microprocessor with volume production expected in the
second half of this year. Specific pricing and availability will be
announced separately by IBM and Motorola.
